I wish you would do more of these.
I started out playing 10-20 limit many years ago. I didn't know much but I was winning because the other players were so bad. At my local card room they occasionally try to start a 15-30 game. I always volunteer to start it but it never gets going.
BTW, what would you buy in for in 30-60? I used to buy in for $500 in 10-20. In the wild 15-30 games at Speaking Rock (Reeking Sock) in El Paso I would buy in for $800 I think. I would buy in for $1000 if I jumped up to 20-40.
There was a lot of drug money being laundered in that game, and the drug people didn't mind if a few of us straight and narrow players took a little of it off the table by the end of the night.
